Problems solved by technology
There is no requirement for the remaining service life of the axles used for loading under the existing planned repair mode. It is only required to be overhauled or the quality of the new system is qualified. When the railway freight cars are overhauled, the remaining service life of the axles cannot be allocated accordingly to control the freight cars. The number of overhauls is reduced, thereby reducing the overhaul cost of trucks

Embodiment Construction
[0047] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
[0048] figure 1 It shows the basic flowchart of the management method for the train axle based on the remaining service life provided by the embodiment of the present invention, as shown in figure 1 As shown, when a train is replacing axles in batches, the remaining service life of each axle suitable for the train in the qualified axle storage area can be obtained first, and a variety of wheel axles suitable for the train to be replaced can be formulated according to the remaining service life of each axle. The second candidate installation scheme, in the various second candidate...

The embodiment of the invention provides a train axle management method based on the remaining service life. The method comprises: obtaining the remaining service life of each axle in axles of a trainto be subjected to part replacement; determining a plurality of second to-be-selected installation schemes of the wheel axle suitable for the to-be-replaced train on the train; calculating the same part service life difference between the highest remaining service life and the lowest remaining service life of the wheel shaft in each scheme in the plurality of second to-be-selected installation schemes; and setting the second to-be-selected installation scheme with the minimum service life difference of the same parts as a secondary installation scheme. The train can install and configure theaxles according to the set secondary installation scheme, so that the remaining service lives of all the axles are minimum, and the maintenance cost can be reduced when maintenance and axle replacement are reduced.
Description
technical field [0001] The invention relates to the inspection and maintenance of railway freight cars, in particular to a method and system for managing train axles based on the remaining service life. Background technique [0002] There are two maintenance modes for railway wagons, namely, planned preventive maintenance and conditional maintenance. All railway wagon maintenance units in China adopt the planned maintenance mode, while conditional maintenance belongs to the direction of future development and is still in the technical research stage. The "remaining service life" of a railway freight car refers to the time period or mileage from the current time point to the next time it is dismantled from the vehicle for maintenance or replacement according to the standard. Axle refers to a railway wagon component consisting of 1 axle, 2 wheels, 2 bearings and corresponding accessories. The remaining service life of the new axle is different from that of the overhauled axle...
